Abstract
The present application discloses a liquid crystal lens. The liquid crystal lens comprises: a first electrode; a second electrode; a liquid crystal layer located between the first and the second electrode; a third electrode, located at a side of the first electrode away from the liquid crystal layer; and a driving means. The driving means is configured to: in a 3D display mode, apply voltages to the first and the second electrode to generate an electric field, such that liquid crystal molecules in the liquid crystal layer are deflected to a first state and form a plurality of lens units, and when switching from the 3D display mode to a 2D display mode, apply voltages to the first and the third electrode to generate an electric field, such that the liquid crystal molecules in the liquid crystal layer are deflected to a second state and form no lens unit.
